Problem installing MSDE

I'm having problems installing MSDE on a windows XP maching. Running setup with the verbose script gives me this:

Property(C): OriginalDatabase = C:\MSDERelA\Setup\SqlRun01.msi
Property(C): UILevel = 3
Property(C): ACTION = INSTALL
=== Logging stopped: 04/09/2007 14:17:38 ===
MSI (c) (A4:AC) [14:17:38:817]: Note: 1: 1708
MSI (c) (A4:AC) [14:17:38:817]: Product: Microsoft SQL Server Desktop Engine -- Installation operation failed.

MSI (c) (A4:AC) [14:17:38:828]: MainEngineThread is returning 1603

This is just the last little bit I can post the whole thing if necessary. The installation stops and rolls back anyone have any idea what's causing this to fail? The server service is started and running normally.....

Try to reboot the machine and give a try to reinstall it......refer this link might be useful
